As a building material, Merbau is a contentious option, as its development is not sustainable.

A main factor in this is the lengthy maturity rate of the tree, about 75-80 years, and even in wealthy woodlands with merbau, individual trees are scarce and difficult to get through.

Therefore, logging merbau without harming the surrounding area is very hard.

However, this does not pose a issue for accessibility; in the Australian marketplace merbau timber is still readily available.

There are three main steps involved in the production of merbau timber decking.


1. SAWMILL -A lumber cutting plant is either a sawmill or a lumber mill. Modern sawmills, based on standard or custom dimensions, use a motorized saw to cut logs lengthwise to produce lengthy and cross-to-long parts.


2. KILN DRY – Kiln drying is a standard practice in wood production facilities and is used to efficiently decrease green lumber moisture to "workable" range levels — moisture content that will not end in the variety of problems that may be caused by excess moisture concentrations in wood. We make sure that we bring kiln dried merbau timber decking.

Why is it important kiln dry timber?

"Wet" or green wood doesn't function well for anything from campfires to building equipment. His effectiveness as a green lumber can be unpredictable due to the inevitable loss of moisture after the living tree is felled. As it dries, wood can twist, crack, warp, and shrink in its physical size, making it less than ideal for building, flooring, or woodworking.


3. Cutting & Moulding – This is the final step. This is the way timber decking is shaped. A decorative function will be added and the final shape will be given prior to packaging.
